HASP-LOCK.

Patented Oct. 17, 1905.

Application filed June 4, 1903. Serial No. 160,005-

To (071/ whom, it may concern.- Be it known that I, THEODORE C. PROUTY,

a citizen of the United States, and a resident of Albion, county of Calhoun, and State of .Michigan, have invented a new and useful Improvement in Hasp-Locks, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to hasp-locks, and particularly to that class of such locks in which the lock forms a part of or is secured to the hasp itself.

The object of the invention is to provide a combined hasp and lock of economical construction and simple in its operation.

Said invention consists of means hereinafter fully described, and particularly set forth in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure 1 represents a front elevation of a combined hasp and lock embodying my invention, showing a part of a door and jamb to which the hasp and staple are illustrated as respectively secured. Fig. 2 represents a side elevation of said hasp and lock, showing said door and jamb parts in section. Fig. 8 represents the lock proper with the rear portion of the casing removed to disclose the interior mechanism of the device. Fig. A represents a similar view show ing said parts in a second position. Fig. 5 represents a vertical longitudinal section of the lock-casing, showing the interior mechanism as viewed from the front, the front casing portion or cap being removed. Fig. 6 represents a vertical axial section of the lock proper, taken on the plane indicated by line VI VI, Fig. 5. Fig.7 represents a horizontal axial section taken upon the plane indicated by line VII VII, Fig. 5. Figs. 8, 9, and 10 represent elevational views of details of the locking mechanism, and Fig. 11 represents a top plan View of the carrier-slide and tumblers attached thereto.

The hasp-bar A is formed with an integral end circular-portion (1 upon which is secured in any suitable manner a cylindrical cap a, which is formed with a central elongated inwardly-projecting shell a open at both ends and forming a central opening a through the cap a. The central part of circular portion a is also formed with an elongated opening for receiving the projecting shell a anopening through the entire casing formed by the cap a and circular portion a being thus formed. The upper and lower portions of shell (0 are formed with vertically alined openings a, adapted to receive and permit of the passage of the head of an oscillatory bolt B transversely of the opening (4 This bolt is mounted upon a pivot-pin b and has secured to it an operating-spring, which tends to keep it in its open position, as shown in Fig. 3, one end of such spring being secured to the bolt, as shown, and the other end bearing against the contiguous portion of the interior of the cap. Said bolt is provided with a downwardly-extending arm formed with a recess 6 preferably made of gear-tooth form and which engages a gear-tooth 0, formed upon the end of a carrier-slide C, Fig. 8. The opposite end of said slide is formed with a projecting rest 0', which rests upon a flat stud d, riveted upon the inside of the casing,'as shown in Figs. 3, 4, and 5, the first-mentioned end being supported upon a pin d, fixed transversely of the easing. It will therefore be seen that the carrier-slide may be shifted longitudinally upon bearings formed by the pin d and the stud (Z. Oscillatorily mounted upon each side of said slide are two tumblers e, 0', c and 6 tumblers e, e, and 6 being identical in form, 0 having a slight variation, hereinafter described. The axes of oscillation of these tumblers coincide and lie in a pivot-pin C, passing through an eye 0 located near the toothed end of the slide, Fig. 8. Each tumbler is formed witha plane end slot which is adapted to receive the stud (Z and is provided with a spring 0 tending to move said slotted end downwardly, one end of such spring being secured to its respective tumbler and the other end pressing upwardly against a transverse pin a, secured near the upper edge of slide C, Fig. 11. is provided with a slot forming a shoulder a and curved surface 0 and the lower edges of tumblers c, 0, c and c with plane surfaces 6 The lower edge of slide C eral lug (Z forming a transverse surface intermediate of the ends of said stud. The opposite end of said tumbler is provided with a downwardlyextending tailpiece a. Projecting through an aperture a and outwardly a little beyond the casing is a spring-button at, having a stud a formed thereon, provided with an inclined surface a Fig. 5.

The slide C, stud, and tumblers form the locking mechanism for operating the bolt, and when thelatter is in its normal position that is, when it is located in a position in which it lies across the keeper or staple opening athe parts assume the position illustrated in Figs. 4 and 5. In this position surfaces 0" fall in the same plane, the tumblers laterally covering the slot forming the shoulder In this position the slots 0 fall be low the stud (Z, and so prevent the endwise displacemcntor longitudinal movement of the slide (J, and hence prevent the movement of the bolt B. The keyhole is formed in a rotatable barrel F and receives a key F This key is provided in its web with three projectinglugs ff f and two intermediate slotsf and f, Fig. 6. Lugs f and f are of a length such that they may be caused upon rotation of thekey to raise tumblers e and 6 so as to bring their end slots into alinement with the stud cl, as shownin dotted lines, Fig. 4:. The slots f and f are of a depth such as to cause the webportions at the bottom thereof to raise tumblers e and 6 into similar positions. Lug f engages shoulder a and moves the slide C longitudinally after theraising of the tumblers, as above mentioned, so as to cause all the end slots 0 to receive the stud, the curved surfaces 0 and e permitting the continuation of the rotation of the key and its subsequent withdrawal from the keyhole. During this operation lugf escapes engagement with slide 0 prior to its contact with the shoulder c by entering the slot forming the latter. Such operation of the locking mechanism causes the tumblers and slide to assume the position shown in Fig. 3, in which the bolt is withdrawn from the staple-opening, the lip a engaging the lug (Z and so locking and retaining its said mechanism and bolt in such described position, the tailpiece a being brought over and into the path of movement of the stud (0 on the button a. To cause the mechanism to reassume its normal or looking position, it will hence be seen that it is only necessary to manually press the button a inwardly, thus releasing the tumbler e from its engagement with the stud (Z, and so permitting the operating-spring b to retract the slide Cand tumblers and the return of bolt B independently of the key F, tailpiece a sliding off the inclined surface a during such retraction. It will thus be seen that a staple or keeper G may be locked in or released from the keeper-receiving opening (0 Rotatably mounted upon the outside of the casing A by means of two pins or lugs ]L /t, Fig. 1, is a plate H,having two tongues it and h, which are adapted to pass transversely of the said opening a and through the staple Gr when the plate is rotated, thus forming a means for temporarily retaining the staple independently of the locking-bolt and mechan ism.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention- 1. In a hasp-lock, the combination of a casing; a keeper, a locking-bolt, and means for operating the latter, received by said casing; and a rotatable plate provided with inwardlyprojecting tongues adapted to engage and disengage said keeper.

2. In a lock, the combination of a suitable casing, a movable bolt, key-operated mechanism for actuating said bolt, and including a series of tumblers, means for locking one of the latter in one of its extreme positions, and a member projecting through the casing and arranged to engage said one tumbler and release same, whereby said bolt may be actuated independently of a key.

3. In a lock, the combination of a suitable casing, a movable bolt, key-operated mechanism arranged to impart a movement to the bolt in one direction, a spring for imparting a movement thereto in the opposite direction, said mechanism includingaseries of tumblers, means for locking one of the latter at the end of its key-operated stroke, and a member projecting without the casing arranged to disengage said one tumbler and permit said spring to return said mechanism and bolt.

4. In a lock, the combination of a suitable casing, a movable bolt, key-operated mechanism arranged to impart a movement to the bolt in one direction, a spring for imparting a movement thereto in the opposite direction, said mechanism including a series of tumblers, a fixed stud, one of said tumblers provided with a lip arranged to engage said stud at the end of its key-operated stroke, and a member arranged to be manually operated and to engage said one tumbler to disengage same from said stud, whereby said mechanism and bolt may be returned by said spring.

5. In a lock, the combination of a casing, a series of connected key-actuated tumblers, means for securing one of same at the end of its key-actuated stroke, and means arranged to be manually operated independently of a key for actuating said securing means to render said one tumbler capable of release.
